Overview
Zone/output expander or DGP — adds supervised inputs or relay outputs (ATS Axon, Challenger DGP, NXG-208N/508N, relay boards).
On Interlogix systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

Before You Service or Replace One
- Sensor SKU — TX-E wireless vs hardwired loop vs 433 MHz expander path.
- Panel online — resolve panel AC/comms trouble before blaming sensor.
- Range — 433 MHz expander or move wireless receiver for distant zones.
- Battery type — use listed cell; replace all batteries in multi-cell devices.
- Tamper — cover fully closed before declaring hardware fault.
